Greco is an Italian wine grape that may be of Greek origin. The name relates to both white (Greco bianco) and black (Greco nero) grape varieties. While there is more land area dedicated to Greco nero, the Greco bianco is the grape most commonly referred to by "Greco". In the Campania region it is used to produce the Denominazione di Origine Controllata e Garantita (DOCG) wine Greco di Tufo.
